[pve-devel] [PATCH qemu-server v2 1/5] enable clipboard parameter in vga_fmt

[Markus Frank <m.frank@proxmox.com>]

added Options to use the qemu vdagent implementation to enable the noVNC clipboard.
When enabled with SPICE the spice-vdagent gets replaced with the qemu
implementation.

This patch does not solve #1406, but does allow copy and paste with
a running X-session, when spice-vdagent is installed.

v2: added pci address to virtio-serial-pci

With this Patch you have the ability to choose which
clipboard-implementation to use when using Spice.
The alternative would be to only allow noVNC
clipboard if no SPICE is running, because qemu cannot use the same
virtserialport twice. This alternative would also disable the ability
to use the noVNC clipboard with VirtIO/VirGL.
